App Setup

Create App here https://developer.twitter.com/en/apps/create

Add Callback URLs to twittersdk:// (For Android SDK)

From App Details goto Keys and tokens and add in res/values/strings.xml

<string name="twitter_api_key">REPLACE_KEY</string>
<string name="twitter_api_secret">REPLACE_SECRET</string>

From App Details goto Permissions -> Edit

Access permission -> Read, write, and Direct Messages
Additional permissions -> Check to true (Request email address from users)
Save

Add INTERNET permission in AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET" />

Add twitter SDK dependency to build.gradle (Module:app)

dependencies {
    implementation 'com.twitter.sdk.android:twitter:3.1.1'
    //implementation 'com.twitter.sdk.android:twitter-core:3.1.1'
    //implementation 'com.twitter.sdk.android:tweet-ui:3.1.1'
}

In Activity

private TwitterAuthClient twitterAuthClient;

Custom Button Click

TwitterConfig config = new TwitterConfig.Builder(this)
    .logger(new DefaultLogger(Log.DEBUG))
    .twitterAuthConfig(new TwitterAuthConfig(getResources().getString(R.string.twitter_api_key), getResources().getString(R.string.twitter_api_secret)))
    .debug(true)
    .build();
Twitter.initialize(config);

twitterAuthClient = new TwitterAuthClient();

TwitterSession twitterSession = TwitterCore.getInstance().getSessionManager().getActiveSession();

if (twitterSession == null) {
    twitterAuthClient.authorize(this, new Callback<TwitterSession>() {
        @Override
        public void success(Result<TwitterSession> result) {
            TwitterSession twitterSession = result.data;
            getTwitterData(twitterSession);
        }

        @Override
        public void failure(TwitterException e) {
            Log.e("Twitter", "Failed to authenticate user " + e.getMessage());
        }
    });
} else {
    getTwitterData(twitterSession);
}

private void getTwitterData(final TwitterSession twitterSession) {
    TwitterApiClient twitterApiClient = new TwitterApiClient(twitterSession);
    final Call<User> getUserCall = twitterApiClient.getAccountService().verifyCredentials(true, false, true);
    getUserCall.enqueue(new Callback<User>() {
        @Override
        public void success(Result<User> result) {

            String socialId = "", firstName = "", lastName = "", gender = "", birthday = "", email = "", picture = "";

            User user = result.data;
            socialId = user.idStr;
            email = user.email;
            /*picture = user.profileImageUrlHttps.replace("_normal", "");
            firstName = user.name;
            lastName = user.screenName;*/

            try {
                firstName = user.name.split(" ")[0];
                lastName = user.name.split(" ")[1];
            } catch (Exception e) {
                firstName = user.name;
                lastName = "";
            }

            Log.e("Twitter", "SocialId: " + socialId + "\tFirstName: " + firstName + "\tLastName: " + lastName + "\tEmail: " + email);
        }

        @Override
        public void failure(TwitterException exception) {
            Log.e("Twitter", "Failed to get user data " + exception.getMessage());
        }
    });
}

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (twitterAuthClient != null) {
        twitterAuthClient.onActivityResult(requestCode, resultCode, data);
    }
